I have about 7gb total music. The problem is I only have a 4gb clip zip. I have an 8gb card in it right now because my 16gb card is in my fuze+. I was just curious if it's possible to combine all the files into one single list?

i don't think they will all fit on the 8gb. right now i have the files split using database>track>all tracks and can bring up a list using the bottom button which should work fine for now. just have to get used to pressing power instead of back to get back to now playing screen.

There's a few ways to create a playlist using both memories without using the database in Rockbox. Using the playlist catalog context menu when you first boot to "Create Playlist" creates a playlist of all the audio files on the player.

It's also possible to create that playlist by inserting the files from each memory into a playlist and saving that. Once you get familiar with how to deal with playlists in Rockbox it becomes really simple to create playlists using any file or folder from anywhere on the player.
